Hot Bodies

Jennifer Lopez contorted her body into all sorts of positions this weekend ... rehearsing before her gig at the iHeartRadio Ultimate Pool Party in Miami.

Paul McCartney got a little help from his friend/wife while roasting in the sun.

Paul and Nancy Shevell have been chilling in Ibiza ... where most people are capable of applying sunscreen on their chests without assistance -- but most people aren't Beatles and Knights.

Sure ... 53-year-old Nancy might look kinda like a nursemaid lathering ointment on a patient -- but we're guessing rubbed up 72-year-old Paul ain't complainin'.

Khloe and Kim Kardashian were in a horse race Friday night ... each clearly trying to take the evening with assets that are undeniably spectacular.

Khloe and French Montana got nice and cuddly sailing on the Utopia III in NYC on the Hudson River ... to celebrate K.K.'s 30th birthday ... and her incredible ass clearly made some partiers go full mast.

And then there's Kim ... whose boobs could save perhaps a dozen lives in a nautical emergency.

Oh yeah ...Kris, Kylie and Kendall Jenner were there too.

Now that's a party we could get behind.

Michelle Rodriguez can really take a lickin' ... because she threw her body around like a circus performer ... diving, flipping and romping around on a yacht in Italy, but her bikini clung to her body tighter than Cara Delevingne ever did.

Chrissy Teigen must not have wanted her bra to set off any security alarms at the airport, that’s the only reason we can think of why she left it at home!

We could explain to you in detail what her boobs look like with no bra, in a see-through white shirt, swinging their way through LAX ... but it’s better if you just watch it yourself. Trust us.

The Jay Z and Beyonce tour kicked off in Miami Wednesday night and while we were quick to enjoy Bey's asstastic outfit ... our newsroom came up with ulterior interior motive.

Is it possible Beyonce showed off her ass, so she wouldn't have to worry about accidentally showing off something else? TMZ Health investigates ...

Vine star Jessica Vanessa knows how to draw a crowd ... just shake dat ass!!!

Vanessa was at a Vine meet-up in Pan Pacific Park in L.A. Wednesday, where she chatted with our photog ... completely unnoticed by the crowd ... that is, until she decided to show off her infamous twerking skills.

Once the cheeks began to move, the crowd did too ... and before long she was surrounded by a gaggle of fans.

As the old saying goes ... if you shake it, they will come.

Paris Hilton issued a public service reminder Wednesday ... she's still freakin' HOT as hell!

Hilton was strutting around the set of her new music video, wearing a slew of crazy sexy black leather outfits. The video was for her song, "High Off My Love," and Paris recently went looking for "gorgeous, sleek models" via social media.

It's unclear what actually happens in the video, but she could just stand there for four minutes and we'd watch.

Beyonce and Jay Z wasted a ton of money filming a full-length trailer promoting their On the Run Tour because all they had to say was ... BEYONCE SHOWS OFF HER BOOOOOOOTY!!!!

The couple kicked off their tour in Miami Wednesday night and the show-stopping moment was definitely when she performed the song "Naughty Girl" ... wearing a costume with the ass cut out.

This is the best video we've seen featuring Beyonce since ...

Courteney Cox just turned 50.

Anna Faith Carlson, the smoking hot model who bares a strong resemblance to Elsa from "Frozen," was spotted out on the beach in Florida this week ... with a body that is anything but G-rated.

She's clearly not let herself go.

Jeremy Meeks can't erase his criminal past ... but he can erase his gang-style tats with the help of a tattoo removal company that's offering him free laser treatments ... and cold, hard cash for his bail.

The honchos at LaserAway say they've been following Meeks' story ... and were touched by comments from his mom ... about how her son has been stereotyped by the ink on his body.

But the convicted felon should think twice before accepting the offer ... as we reported, he's getting bites from modeling companies that like the body art ... because it's gangster-chic.

If he goes through with the removal ... the company says it will also pony up $20K toward his $900,000 bail.

The company may do better with Melanie Griffith.

Get excited, fellas ... we've got hot supermodel Jessica White talking whether or not models take showers with each other after photo shoots!

Get less excited, fellas ... we've also got her talking about wanting to get pregnant.

:(

Posing with a strategically placed No Entry sign, model Cara Delevingne served up a subtle reminder to the guys which way she goes.

Mercedes "MJ" Javid swears she hasn't been photoshopped, she really did drop 20 lbs., and she tells TMZ ... she did it the old fashioned way -- lots and lots of sex ... and some traditional exercise.

The "Shahs of Sunset" star says she's seen all the haters accusing her of doctoring the pics from a recent swimsuit shoot -- but says her real secret is simply banging the weight away.

Best of all ... MJ claims the more pounds she shed, the more sex she had -- and the more sex she had, the more calories she burned. The least vicious cycle ever!

She admits cutting back on hard partying and late-night boozing definitely helped too ... along with hiking, biking, tennis and dodge ball -- but says she's definitely sticking to her sex diet. She says bluntly, "I'm too pretty to be fat!"

Taylor Lautner hit the beach looking really really ... different? The 'Twilight' stud seems to be about a six-pack shy of the guy we're used to seeing.

But what's most disappointing about Taylor's new physique is -- it's still at least 10 times better than the rest of ours. Damn werewolves!
